Excavation-free technology was relatively late to emerge compared to other technologies. However, it is noteworthy that over the past two decades, there has been a remarkable advancement in both theory and construction techniques. Excavation-free technology is an extremely important method for urban pipeline construction, offering numerous unique advantages.

Trenchless technology is widely utilized overseas and is increasingly gaining popularity domestically. It allows for crossing over highways, railways, rivers, and even beneath buildings without disturbing the ground surface, making it a safe and efficient method for environmental protection construction.

Non-destructive excavation technology does not disturb the soil layers above the pipeline, thus preventing differential deformation at the pipe joints and extending the pipeline's lifespan compared to excavation methods.

The use of non-excavation technology under buildings can save a significant amount of land acquisition and relocation costs, reduce the need for relocation housing, shorten pipeline lengths, and offer substantial economic benefits.
